Abstract (en)

[origin: WO9412102A1] An insertable intracavity probe (10) for use in magnetic resonance imaging of an area of interest in a relatively inaccessible region of the body is disclosed. The probe has an internal pickup coil (18) carried at the distal end of a shaft (12) for rectal insertion of the coil and an inflatable anti-migration cuff (72) to hold the probe in position and prevent outward migration thereof during a procedure. The anti-migration cuff (72) is carried on an outer sleeve (16) which is slidably and rotatably mounted on the shaft. The coil (18) is carried on a resilient tip structure (38) at the distal end of the shaft which is flexible in the plane normal to the plane of the coil. Deflection of the coil assembly is controlled by a pair of control lines (46 and 48) attached to the distal end of the tip structure. The lines may be selectively tensioned to deflect the coil in the direction of tension by a thumb wheel control (56) at the handle (26) of the probe.
